What are the odds for this trick?
If you are not familiar with it, 4 jumbo cards are cut into 4ths.
They are placed on the table in a 4 by 4 grid. Some cards are face up, some face down. Spectators pick a row or column and it is flipped over onto the adjecent row.
When all is said and done, 4 pieces are facedown and match the prediction.
My question is how many possiblities can be made with the 16 pieces.
The add states "out of 720 possible ways a spectator can turn over 16 jumbo quarter cards,"
Is this true?
